HAY-:PRESS Specification of Letters Patent.

Patented Mar. 17, 1914.

To all @clio/nz it may concern.'

Be it known that we, JOSEPH DMN and HERBERT B. Srninir, citizens of the United States, residing at Ottumwa, in the county of vWapello and State of Iowa, have invent ed certain new and useful Improvcmcnts in Hay-Presses, of which the following is a specification, reference being had to the accompanying drawings.

Our invention relates to hay presses, and has for its object to provide certain improvements therein, such improvements having to do more particularly with the mechanism for supplying the hay to the baling chamber.

To this end our invention consists in providing .improved means for condensing thc hay before its introduction into the compression chamber and in providing an improved construction of feeder for carrying the hay down into the con'irnession chamber, which is so constructed as to yield in case the feeder or beater head encounters an unyielding obstacle, thereby preventing breakage.

We accomplish the objects of our invention as illustrated in the drawings and as hereinafter described.

that we regard as new is set forth in the claims.

ln the drawings,-Figure 1 is a side elevation of the principal parts of a hay press embodying our invention; Fig. 2 is an enlarged side view, the tiy-wheel being rcmoved; and Fig. 3 is a plan view of the parts shown in Fig. 2.

Referring to the d1awings,1t indicates the frame of the press, which vis provided, as shown, with a compression chamber' 5 and an extension 6 in which the several charges are pressed together in forming the bale.

7 indicates a plunger, which rcciproeates in the compression chamber in the usual way and is driven by a pitman S which is connected by wrist-pins 9 with gears 12, mounts ed on studs 14: at opposite sides of the frame, as shown in Fig. The gears 1Q are driven from a drive-shaft 15 through intermediate gears 16, 17 and 18, the gears 17-1S being mounted on a countershaft 20 arranged parallel with the drive-shaft- 15. 2l indicates a belt-pulley mounted on the driveshaft 15, by which it may be driven from any suitable source of power.

22 indicates a fly-wheel preferably mounted on the opposite end of the shaft 15.

Obviously, by the rotation of the gears 1Q the plunger may be reciprocated in the comln'ession chamber.

23 indicates thc usual opening leading into'the compression chamber, which opening is surrounded on three sides by a feeding table Q1.

indicates an open frame, of angle-iron or other suitable material, which is secured adjacent to one of the side edges of the openmg Q3, rising vertically at such side edge, as shown in Figs. 1 and Said frame substantially ol the same length as the feeding opening 23 and is provided with a number of rods 26 arranged horizontally and extending :torward beyond thc end thercofv'. c., toward the drive-shaft 15--in the manner shown in Fig. 1. As best shown in said ligure, the several rods E2G are parallel and their forward or outer ends extend a considerable distance beyond thc frame 25.

2T indicates a second frame, similar to the frame 25, which extends across the rear edge of the feeding opening)` Q3 adjacent to the frame Q5, standing at right angles to said frame 9.5, as shown in Fig. 2. The frame 27 is also provided with a series ol rods or bars similar to the rods Qt with thc exception that the rods QS, for the purpose of facilitating the reversal oit the condensing apparatus as hereinafter referred to, extend equally from cach side of the frame 27, in the manner shown in Fig. 3. Both the frames 25 and 2T are stationary and with their respective rods '2G 28 act as barriers or guards to keep the hay thrown over the feeding opening in place when it is condensed, as hereinafter described.

'29 indicates an angular frame, which is provided with projecting rods or bars 30 31 at its ends, said rods intel-lacing with the rods 26 Q8, respectively, in the manner shown in F ig. Il, thus fori'ning a rectangular inclosure which, when extended to its greatest size, comprehcnds the feeding opening 23 and a consitflerable part of the feeding table 24. The illustration in Fig. 2l shows this inclosurc extended, to its greatest capaeity. The frame Q9 is capable of being moved diagonally toward the feeding opening into the position shown in dotted lines in Fig. 3, at which time it registers substantially with two of the side edges of the feed* ing opening, the rods 30 31 then extending a considerable distance beyond the rods 26 28,

respectively. By moving the frame 29 up toward the feeding opening in this manner, it will be apparent that the hay resting on the feeding table and over the feeding opening will be condensed so that it will more readily pass through the feeding opening, thus relieving the operator of the necessity of manually condensing the hay in order that the automatic feeding device will carry it all into the compression chamber.

In order to automatically operate the frame 29, it is mounted on parallel bars 32 33, respectively, carried on vertical shafts 34 35, respectively, suitably j ournaled at the forward side edge of the table 24, shown in the drawings. The shaft 34 is at the transverse center of the table, the shaft 35 being at one of the side edges thereof. A supplemental bearing 36 is preferably provided at the opposite side edge of the table to permit of the reversal of the position of the frame 29 so that it may be used at the other side of the machine. By this construction the swinging of the bars 32 33 will move the frame 29 diagonally toward and away from the feeding opening 23, holding it at all times parallel with the side and rear margins thereof.

, 37 indicates a crank carried by the shaft 35 and connected by a connecting rod 33 with a slotted arm 39, which is connected by a pivot 40 at one end with the frame of the press, as shown in Fig. 2. The arm 39 is provided with a slot 4l which receives the wrist-pin 42 of a crank 43 extending through the stud 14 and connected to gear l2, said wrist-pin being arranged to slide in said slot as the gear l2 rotates. Said gear is arranged to rotate in the direction indicated by the arrow in Fig. 2. By this construction the rotation of the gear l2 will swingV the arm 39 slowly to the left, but will return it quickly, as on the return movement the wrist-pin 42 will be nearer the pivot 40. `lVhen the arm 39 is swung to the right, the crank 37 will be carried in the same direction, thereby rocking the parallel bars 32 33 to the right and moving the frame 29 up toward the feeding opening. rlhus the frame 29 will be automatically operated to condense the hay and permit of its being carried more readily into the compression chamber.

In order to automatically force the hay down through the feeding opening, we provide a feeding device comprising beaterarms 44 which are fulcrumed intermediately upon a casting 45 mounted to rock about trunnions which project inwardly from blocks 5G placed at the top of the frame of the press, as shown in Fig. 3. At their outer ends the beater-arms 44 carry a beaterhead 47 and at their inner ends they are connected by pitmen 43 with the rear end of the plunger 7, the arrangement being such that as the plunger advances into the compression chamber the beater-head is swung up out of operative position, and when the plunger is withdrawn said beater-arm is carried down into the compression chamber. In order to permit the beater-head to yield if it encounters a fixed obstruction, 'the beater-arms 44 are not fiXedly connected with the casting 45 but rest thereon and are normally held in operative position by a spring 49, the lower end of which bears against a plate 50 which rests upon the beater-arms 44, its outer end bearing against a washer 5l carried by a pin 52 and held in place by a nut 53. The pin 52 is secured at its inner end to the casting 45, as shown in Fig. By this construction, when the beater-head encounters extraordinary resistance the spring 49 permits it to yield, thereby avoiding breakage. In order to prevent endwise movement of the beater-arms relatively to the casting 45, said arms are provided with laterally-projecting pins 54 which fit in slots 55 in the sides of the casting or yoke 45, as shown in Fig. 2. By adjusting the nut 53, the tension of the spring 49 may be regulated. Ve thus provide a very compact and simple construction for yieldingly supporting the beaterarm and one in which there is no end thrust on the beater-arm when it leaves its seat in the yoke or casting. Furthermore, we also provide a simple and economical construction for feeding the hay and one by which the hay is maintained in rectangular form at all times during the condensing operation and consequently is condensed more uniformly, thus facilitating the feeding of the hay into the compression chamber and insurino` uniformity through the compacted sections of the bale. n
